No the mouse did, it was too heavy and the mouse was too big to hold as I wanted so it never felt right.
Went after I stopped using it, though I have a constant tingle in wrist. I'm not gonna stop using pc's so I don't see the point in caring. Occupational thing and we're all gonna end up as robots anyway so its all good.
i never understood how those guys, anyone infact, uses the Boomslang. it's one very weird shape, i've tried it myself and no matter what i try and no matter how long i try i simply couldn't use that shape. how it all became popular is beyond me.
on a more serious note, aiming depends the skill=experience u have (not with women though :P)
for instance I use mx518, but because my total spent time on online q3/ql play is abt 3-4 months only, my aim is fuckin bad, got outaimed on ql all the time -not mices fault
